Tras las huellas de la orden jerónima en la ciudad de Zamora. Estudio y restitución gráfica del Monasterio de San Jerónimo de Montamarta

[ES] Una de las mayores pérdidas del patrimonio artístico de la ciudad de Zamora ha sido la desaparición del monasterio de San Jerónimo que, fundado en el siglo XVI, representó el edificio más grande de la ciudad durante varios siglos. Gracias al análisis de las principales fuentes gráficas y escritas, se ha llevado a cabo la restitución de este espléndido inmueble renacentista, ejemplo de los mejores técnicos locales y de los más poderosos mecenas del momento. De los resultados gráficos se extraen aclaraciones del modo de articular los accesos, así como el análisis de sus proporciones y de la articulación de los espacios de este edificio desaparecido. Asimismo, se pretende abordar el estudio de su implantación urbana, su proceso constructivo y su tipología dentro de la casuística de los monasterios jerónimos de la Corona de Castilla.[EN] One of the greatest losses of the artistic heritage of the city of Zamora has been the disappearance of the monastery of San Jeronimo that, founded in the sixteenth century, represented the largest building in the city for several centuries. Thanks to the analysis of the main graphic and written sources, the restitution of this splendid Renaissance building has been carried out, an example of the best local technicians and the most powerful patrons of the moment. From the graphic results clarifications of the way to articulate the accesses are extracted, as well as the analysis of their proportions and the articulation of the spaces of this disappeared building. Likewise, it is intended to address the study of its urban implementation, its construction process and its typology within the casuistry of the Hieronymite monasteries of the Crown of Castile.López Bragado, D.; Lafuente Sánchez, VA.; Úbeda Blanco, M.

Influence of metallic artifact filtering on MEG signals for source localization during interictal epileptiform activity

Objective. Medical intractable epilepsy is a common condition that affects 40% of epileptic patients that generally have to undergo resective surgery. Magnetoencephalography (MEG) has been increasingly used to identify the epileptogenic foci through equivalent current dipole (ECD) modeling, one of the most accepted methods to obtain an accurate localization of interictal epileptiform discharges (IEDs). Modeling requires that MEG signals are adequately preprocessed to reduce interferences, a task that has been greatly improved by the use of blind source separation (BSS) methods. MEG recordings are highly sensitive to metallic interferences originated inside the head by implanted intracranial electrodes, dental prosthesis, etc and also coming from external sources such as pacemakers or vagal stimulators. To reduce these artifacts, a BSS-based fully automatic procedure was recently developed and validated, showing an effective reduction of metallic artifacts in simulated and real signals (Migliorelli et al 2015 J. Neural Eng. 12 046001). The main objective of this study was to evaluate its effects in the detection of IEDs and ECD modeling of patients with focal epilepsy and metallic interference. Approach. A comparison between the resulting positions of ECDs was performed: without removing metallic interference; rejecting only channels with large metallic artifacts; and after BSS-based reduction. Measures of dispersion and distance of ECDs were defined to analyze the results. Main results. The relationship between the artifact-to-signal ratio and ECD fitting showed that higher values of metallic interference produced highly scattered dipoles. Results revealed a significant reduction on dispersion using the BSS-based reduction procedure, yielding feasible locations of ECDs in contrast to the other two approaches. Significance. The automatic BSS-based method can be applied to MEG datasets affected by metallic artifacts as a processing step to improve the localization of epileptic foci.Postprint (published version

El parque de la Marina Española: de paseo arbolado del primer ensanche de Zamora a principal espacio verde de la ciudad

El parque de la Marina Española representa el principal espacio verde de la capital zamorana. Su origen se remonta al paseo arbolado que embellecía la carretera de Valladolid a mediados del siglo XIX. Con la llegada del nuevo siglo, el paseo se peatonalizó y amplió, para convertirse en un incentivo de la construcción del primer ensanche de la ciudad. El presente trabajo pretende analizar las transformaciones que sufrió este espacio verde a partir de la posterior consolidación del ensanche, momento en que se plantearon proyectos para su ampliación como parque urbano o como gran plaza del ensanche, aunque ninguno llegaría a concretarse. No sería hasta la década de los setenta cuando se urbanizaría el parque de forma unitaria, aunque segregado por la calzada que lo atravesaba, cosa que se subsanó en la década de los noventa, cuando un nuevo proyecto modificó este espacio dotándole de la imagen que muestra en la actualidad

Numerical modeling of tidal propagation and frequency responses in the Guadalquivir Estuary (SW, Iberian Peninsula)

A three-dimensional numerical model, based on Delft3D code, has been implemented and calibrated in the mesotidal Guadalquivir Estuary (Spain), a tidally-driven estuary due to the reduced freshwater discharges (25 m3s-1 year-round average), which are subject to human regulation at the dam located at its head. The model has been applied to study in detail some estuarine features for low freshwater discharges: the first one is the non-linear interaction of semidiurnal constituents, which results in a tidal amplification factor (ratio of local amplitude to the amplitude at the mouth) that depends on the spring-neap tidal cycle, with markedly larger values during neap tides. The second one is the analysis of tidal resonance in the estuary, extending previous studies on the topic, which shows that resonance occurs at near-diurnal frequencies. The peak of resonance decreases in magnitude and shifts towards lower frequencies as friction increases, either by increasing the friction coefficient itself or the amplitude of the tide.Funding for open access charge: Universidad de Málaga/CBUA

The Sotelo hospital in the city of Zamora and the urban regularization of its surroundings

[ES] El hospital de Sotelo representó el mayor centro asistencial de cuantos existían en Zamora en el momento de su fundación en 1526. Con el paso del tiempo cesó su uso hospitalario, siendo ocupado por toda una serie de usos educativos y administrativos para los que el edificio no estaba concebido. Su situación era estratégica, entre dos de las principales calles de la ciudad. Con el paso de los siglos, esta cualidad fue también su verdugo, ya que los planes de alineaciones de inicios del siglo pasado exigieron la demolición parcial del edificio, como finalmente sucedió. Se pretende analizar gráficamente el edificio, así como exponer los condicionantes urbanísticos que provocaron su derribo parcial, al igual que los determinantes sociales y políticos que provocaron su demolición definitiva después de cuatrocientos años de existencia.[EN] The Sotelo hospital represented the largest healthcare center of all those that existed in Zamora at the time of its foundation in 1526. With the passage of time its hospital use ceased, being occupied by a whole series of educational and administrative uses for which the building did not it was conceived. Its location was strategic, between two of the main streets of the city. Over the centuries, this quality was also its executioner, since the alignment plans of the beginning of the last century demanded the partial demolition of the building, as it finally happened. It is intended to graphically analyze the building, as well as to expose the urban conditioning factors that caused its partial demolition, as well as the social and political determinants that caused its definitive demolition after four hundred years of existence
